Dear Neha, Dont blame Islam. Islam does not teach to do such a evil act. Indeed it tell the human than if someone killed the man/women it mean he killed the entire humanity.
Therefore, It is not Islam fault, it is the Fault of labelled Muslims who doing such a evil act with mis-understanding of Islam.
Islam is not a new religion it is still living and occupaying this world for last 1400 years. No one can destroy it becoz its acknowledge by our only Creator. So Dont get doubt about it
